What is Adenosine deaminase?
Adenosine deaminase (ADA) is a protein produced by body cells and is associated with lymphocyte activation. This test measures the amount of adenosine deaminase in pleural fluid. Elevated ADA levels indicate tuberculosis infection of the pleurae. It also helps to determine infections in other fluids such as peritoneal fluid or cerebrospinal fluid (CSF).
